Mix together air, fuel, and heat and you get combustion, the chemical reaction that powers most engines in planes, trains and automobiles. And if you throw in some ionized gas (plasma), it turns out, you can sustain combustion ...

DARPA theorized that by using physics techniques rather than combustion chemistry, it might be possible to manipulate and extinguish flames. To achieve this, new research was required to understand and quantify the interaction ...

(Phys.org) -- Environmental scientists at Harvard have discovered that the Arctic accumulation of mercury, a toxic element, is caused by both atmospheric forces and the flow of circumpolar rivers that carry the element north ...

Replacing gasoline and diesel with plant-based bio fuels is crucial to curb climate change. But there are several ways to transform crops to fuel, and some of the methods result in bio fuels that are harmful to health as ...

A collaborative, six-year study of carbon dioxide (CO2) levels in Beijing and surrounding provinces suggests that combustion efficiency, a component of overall energy efficiency, is improving in the region.
